What You Get in Each 2025 GMC Yukon Trim
The 2025 GMC Yukon comes in five main trim levels: SLE, SLT, AT4, Denali, and Denali Ultimate. Each step up adds features, comfort upgrades, and styling changes. The SLE is the base model with cloth seats, a standard 10.2-inch touchscreen, and essential safety features. The SLT adds leather upholstery, a power liftgate, and upgraded audio. The AT4 is built for off-road capability with skid plates, all-terrain tires, and a locking rear differential. The Denali focuses on luxury with premium leather, a panoramic sunroof, and ambient lighting. The Denali Ultimate is the highest trim, adding a power sunroof, upgraded suspension, and exclusive interior finishes.
All trims seat up to nine passengers in a three-row configuration, though the Denali and Denali Ultimate offer a two-row layout with more spacious seating. Cargo space ranges from 25.5 cubic feet behind the third row to 122.7 cubic feet with all rows folded, depending on the configuration you choose.

Engine and Powertrain Options
The standard engine across all 2025 Yukon trims is a 5.3L EcoTec3 V8 that produces 355 horsepower and 383 pound-feet of torque. This engine pairs with a 10-speed automatic transmission and comes with either rear-wheel drive or all-wheel drive. The 5.3L is fuel-efficient for its class and handles towing up to 8,000 pounds.
A 6.2L V8 engine is available on the SLT, AT4, Denali, and Denali Ultimate trims. This larger engine produces 420 horsepower and 460 pound-feet of torque, improving acceleration and towing capacity to 8,400 pounds. The 6.2L also uses the same 10-speed automatic and offers the same drivetrain choices. Fuel economy is lower with the 6.2L, but the extra power appeals to buyers who tow frequently or want stronger performance.
Both engines support GM's OnStar system with 4G LTE connectivity and remote vehicle features through the GMC app. Transmission fluid and engine oil capacities vary slightly between engines, so check your owner's manual for maintenance specifics.
Interior and Technology Differences by Trim
The SLE comes with cloth seating, a 10.2-inch touchscreen with Apple CarPlay and Android Auto, and a six-speaker audio system. Climate control is manual, and the steering wheel is not heated. The SLT upgrades to leather-trimmed seats, adds a heated steering wheel, and includes a power liftgate. The infotainment system remains the same, but SLT buyers can add a navigation package.
The AT4 keeps the SLT's leather seats and adds unique interior trim with a rugged aesthetic. The Denali introduces premium leather, a 12.3-inch digital instrument cluster, and a 10.2-inch touchscreen with wireless Apple CarPlay and Android Auto. The Denali also includes a Bose premium audio system with 10 speakers, ambient interior lighting, and a power panoramic sunroof on most configurations.
The Denali Ultimate adds a power sunroof (in addition to the panoramic option), upgraded leather with contrast stitching, and exclusive trim colors. All Denali models include a wireless charging pad, heated and ventilated front seats, and a heated second-row bench. Navigation is standard on Denali and Denali Ultimate, while it remains optional on lower trims.
Wheel, Tire, and Exterior Styling Options
The SLE and SLT come standard with 18-inch wheels and all-season tires. The AT4 uses 18-inch all-terrain tires designed for off-road use, with 20-inch wheels available. The Denali rides on 20-inch wheels with all-season tires, and the Denali Ultimate offers 22-inch wheels as an option.
Exterior styling varies by trim. The SLE and SLT use a standard GMC grille and body cladding. The AT4 features a unique grille design, black roof rails, and body-side cladding that emphasizes its off-road purpose. The Denali has a more refined grille, chrome accents, and a sleeker appearance. The Denali Ultimate adds exclusive badging and premium paint options.
All trims offer a choice of exterior colors, including Summit White, Onyx Black, Satin Steel Metallic, and Iridium Metallic. Some colors carry an upcharge. Roof color options (body-color or black) are available on most trims, and a power sunroof is standard on Denali models.
Safety Features and Driver information Across Trims
All 2025 Yukon models include GM's Safety Suite, which consists of forward collision alert, lane-departure warning, and automatic emergency braking. The SLE, SLT, and AT4 include these as standard. The Denali and Denali Ultimate add blind-spot monitoring, rear cross-traffic alert, and a surround-view camera system that shows a 360-degree view around the vehicle.
Adaptive cruise control is standard on Denali and Denali Ultimate, and available on SLT and AT4. The Denali Ultimate adds Super Cruise, GM's hands-free driving system that works on compatible highways. All models include a backup camera, parking sensors, and hill-start information.
Traction control, stability control, and electronic brake distribution are standard across the lineup. The AT4 adds an electronic locking rear differential and skid plates to protect the undercarriage during off-road driving. Brake specifications remain consistent across trims, with four-wheel disc brakes and an electronic parking brake.
Towing, Payload, and Cargo Capacity by Configuration
Towing capacity depends on engine choice and drivetrain. With the 5.3L V8 and rear-wheel drive, the Yukon can tow up to 8,000 pounds. The 6.2L V8 increases this to 8,400 pounds. All-wheel drive reduces towing capacity slightly on some trims. Payload capacity (the weight the truck bed can carry) ranges from 1,400 to 1,600 pounds depending on trim and drivetrain.
Cargo space behind the third row is 25.5 cubic feet on all trims. With the third row folded, space increases to 72.6 cubic feet. With both the second and third rows folded, total cargo space reaches 122.7 cubic feet. The two-row Denali and Denali Ultimate configurations offer more second-row legroom but reduce total cargo space slightly.
Roof load capacity is 150 pounds across all trims. Hitch capacity varies: a Class III hitch (up to 6,000 pounds) comes standard on most trims, while a Class IV hitch (up to 12,000 pounds) is available. Always verify your specific configuration's towing and payload limits in the owner's manual or on the door jamb label.
How to Compare Trims and Choose the Right Configuration
Start by deciding between three-row and two-row seating. If you regularly carry seven or more passengers, the three-row SLE, SLT, or AT4 makes sense. If you prioritize comfort for five to seven people, the two-row Denali or Denali Ultimate offers more spacious seating and premium finishes.
Next, consider your engine needs. The 5.3L V8 is sufficient for most buyers and delivers better fuel economy. Choose the 6.2L if you tow heavy loads regularly or want stronger acceleration. Then evaluate trim features: the AT4 is for off-road capability, while the Denali trims focus on luxury and technology.
Visit a GMC dealer to sit in each trim and test the infotainment systems. Compare the leather quality, seat comfort, and interior layout in person. Check the window sticker (Monroney label) for the exact features, engine, and price of any vehicle you're considering. This label shows all factory-installed options and their costs, making it easier to compare configurations across different dealers.
Frequently Asked Questions
What is the difference between the AT4 and the Denali?
